The utility model relates to a manual screw tightening tool, which is a single head, double head and multi specification movable handle ratchet box wrench (of a fixed hole). The utility model is connected by the main plum blossom sleeve and the slave plum blossom sleeve with different specifications and sizes through the engagement of the female key and the male key of the articulated key. 3. Ratchet is a kind of percussion instrument. The principle is the same as that of an industrial ratchet. It is equipped with a gear that can only rotate in one direction, and several thin wood pieces are installed on the edge of the teeth. When the gear rotates, the teeth touch the veneer to make it bend, and the rear veneer bounces back to its original position and contacts the next tooth. During this period, the friction and impact between the two produce a 'snap, snap' sound. (JiLunJiGouDeZhuYaoYongTu)
